i have been trying to run a maven project as dynamic web project in local server to get hot re-deployment feature, which is currently not available appengine maven plugin with eclipse 我一直试图在本地服务器中将maven项目作为动态Web项目运行，以获取热重新部署功能，目前尚无法使用带有eclipse的appengine maven插件

i referred : https://developers.google.com/appengine/docs/java/webtoolsplatform 我提到了： https : //developers.google.com/appengine/docs/java/webtoolsplatform

this project works fine when running using mvn:appengine devserver command, but we i tried to run on local server, i get the following error 使用mvn：appengine devserver命令运行时，该项目工作正常，但是我们尝试在本地服务器上运行，但出现以下错误

Error occurred during initialization of VM VM初始化期间发生错误

agent library failed to init: instrument 代理程式库无法初始化：instrument

Error opening zip file or JAR manifest missing : /Volumes/My 打开zip文件或JAR清单丢失时出错：/ Volumes / My

any idea what this error means? 知道这个错误是什么意思吗？

Note: the ultimate goal was to some how synchronous changes in src war folder to be present in target directory to avoid stopping and starting server for every changes 注意： 最终目标是确定如何在目标目录中出现src war文件夹中的同步更改，以避免每次更改都停止和启动服务器

any solutions to solve this issue is most welcome! 任何解决此问题的解决方案都非常欢迎！

Thanks 谢谢

To answer the ultimate goal, mvn appengine:devserver already supports reloading: 为了实现最终目标， mvn appengine:devserver已经支持重新加载：

When the server is running, it continuously checks to determine whether appengine-web.xml has changed. 服务器运行时，它将连续检查以确定appengine-web.xml是否已更改。 If it has, the server does a hot reload of the application. 如果有，服务器将对应用程序进行热重载。 This means that you do not need to stop and restart your application because of changes to appengine-web.xml 这意味着由于对appengine-web.xml的更改，您无需停止并重新启动应用程序

Do you have m2e-wtp installed? 您安装了m2e-wtp吗？ It handles web assets being updated in a running container (including the devserver through GPE ). 它处理正在运行的容器（包括通过GPE的devserver）中正在更新的Web资产。
